Disston Molder's Tools

Henry Disston & Sons of Philadelphia made foundry molder's tools until the early 1900s. They appear in a 28-page pocket catalog printed in 1890, Specialties in Tools Manufactured by Henry Disston & Sons. In addition to molder's tools, the catalog included a tree planter, post hole digger, Little Giant pruning hook and saw, several brick trowels, steel rules, marking gauges, steel gauges, steel and combination squares, levels, screw drivers, and Excelsior combination wrench and screwdriver.

Disston levels and squares had previously been made as Disston & Morss (also spelled Morse), and it's possible that the molder's tools were originally marked as Disston & Morss. The last mention I found of Disston molder's tools was in 1916.
